An intranet is the natural evolution of traditional network services. In the last few years, the Internet established a new paradigm for access to information. The intranet borrows this paradigm and applies it on a smaller scale: having an intranet is like having your own internal Web site. The functionality is the same, but the information and pages are ‘internal’ to your organization. In a nutshell, an intranet is a combination of existing LAN and WAN technologies and new Internet technologies.
If yours is a typical district, you probably connect to information on your network using several different client applications to access different back-end services such as application communications, host connectivity, and messaging. You probably use one software package for administrative tasks, another for your database, another for e-mail, and another to explore files and documents. Complicating matters further, you may use a combination of PC and Macintosh desktop hardware for accessing these back-end services. Working this way places more demands on the network since each client application uses up bandwidth and memory-never mind the task of managing the network or training teachers and students on many different user interfaces.
An intranet enables schools or districts to simplify the data access/multiple-client conundrum. All of the clients required to access multiple data stores can be collapsed into one integrated client-your Web browser. With the right server platform, accessing existing back-end services becomes seamless. Users see a single front-end-HTML pages viewed through a Web browser-and can access information easily and efficiently, thanks to hyperlinks. For example, while storing information has always been easy on file servers, accessing it has not been as simple and just finding the right file is sometimes a challenge. With an intranet, that same content is published as Web pages and is available to everyone who has access rights. Teachers, students, and administrators have a simple way to create and distribute information, and they can edit or update it easily. Finally, component technologies like Java® and ActiveX™ provide rich, active rendering of all types of content.
In general a web might be defined as an unstructured client/server network that uses HTTP (HyperText Transfer Protocol - je určený na distribúciu hypertextových dokumentov) as its transaction protocol. The World Wide Web comprises all HTTP nodes on the public Internet. An internal web comprises all HTTP nodes on a private network, such as a corporate LAN or WAN. Note that internal webs, a.k.a intranets, are only logically "internal" to an organization. Physically they can span the globe, as long as access is limited to a defined commun ity of interest.
As a big as a community of interest. Scale is an important factor in web implementation, but it has no bearing on the logical association of clients that make up an intranet. For example, a workgroup with one web server, a company with several hundred web servers, and a professional organization with ten thousand web servers can each be considered an intranet.
While nothing constrains these webs to be "inside" or bounded in any physical sense, size is a significant from a network design perspective. Intranet Design Magazine calls expansive private webs wide-area intranets to connote that WAN economics and technologies apply. We call smaller, in-house webs local-area intranets.
It's a marriage made in CyberHeaven. E-mail is networking's killer app and the foundation of Internet messaging. Intranets inherit SImple Mail Transport Protocol (SMTP, RFC-822) from the TCP/IP suite. On top of SMTP, which enables plain text messaging, intranets use Multipurpose Internet Mail Extensions (MIME, RFC-1521) to carry diverse content. In fact, the MIME content types are the Web's content types; adding a new format such as streaming audio amounts to defining a new MIME type.
All of which is to say that intranets threaten proprietary mail protocols in much the same way they threaten proprietary networking in general.
Browser = Client.
Web server = Server.
CGI, proprietary server API, or Java servlet = Middleware.
Most organizations are run by people working together. How do your employees communicate ? by phone, voice mail, email, fax or by person to person meetings ?
An Intranet can cut down the time your employees spend on routine communication tasks. If you are using email internally you already know the benefits over trying to get someone over the phone. The one problem with using email is that the entire message is usually not conveyed in the first communication. One email usually starts a string of emails back and forth until the other part completely understands your request or message. Instead consider putting forms on your Intranet. Design forms for frequently requested tasks within your organization. For ex. Request for PC repair, stationary reorder from supply room, telephone messages. Have your users fill out the form and make sure the required information is entered by using data validation. This will provide the recipient with an email that is complete with all the required information and save a lot of time.
How much time do your employees spend answering routinely asked questions ? want to cut down the time ? put the information on an Intranet. Don't just put it out there, refer all your callers to your Intranet. for ex. before your travel office answers the phone play a short recorded message saying "For routine questions check our pages on the company Intranet at www..... ."
Do your employees spend time chasing paper ? trying to hunt down paper forms, reports, documents, microfilm ? consider converting these documents to electronic formats using scanners, OCR software or other means. Provide a search interface to these documents using your Intranet. Once users know how easily accessible these documents are over the Intranet, they will prefer the faster solution. Result ? you save time.
Intranet systems can be cheap, easy to use, and secure. The intranet has been deemed the new killer application for business-- by everyone from BusinessWeek to Computer World. This book shows companies how to develop the best plan for implementing an intranet. Revealing the best intranet uses, including its advantages and disadvantages, the book explores how an intranet will fit into the organization, who is going to use it, what it should look like, and other practical strategic issues. Author Mellanie Hills also shares intranet experiences from over twenty companies, using case studies and including actual intranet interface in the book.
Ako funguje Intranet
Intranet využíva nový Internetový protokol HTTP (HyperText Transfer Protocol), ktorý je určený na distribúciu hypertextových dokumentov. Rovnako ako iné TCP/IP aplikácie (napr. FTP, SMTP) aj HTTP je klient/server protokol.
